Release hydrogen ions when dissolved in water. -
✔✔ANSWER ✔✔-Acids
Bind with hydrogen ions in solutions. - ✔✔ANSWER ✔✔-
Bases
critical in maintaining normal body fluid pH -
✔✔ANSWER ✔✔-Buffers
,HCO3 - ✔✔ANSWER ✔✔-Bicarbonate ions
-When acids are present in body fluids, free hydrogen
ions are released and must be controlled for balance.
-Carbohydrate metabolism forms CO2, which is exhaled
by the lungs during breathing.
-Lactic acid production occurs when cells metabolize
under anaerobic (no oxygen) conditions.
-Cell destruction. - ✔✔ANSWER ✔✔-Sources of Acids &
Bicarbonate
-Fluid contains equal # of positive charges, ions with
negative charges.
-Balance occurs by matching rate of hydrogen ion
production with loss. - ✔✔ANSWER ✔✔-Acid-Base
Balance
7.35-7.45 - ✔✔ANSWER ✔✔-Normal pH of arterial blood
,-Fluid and electrolyte imbalances
-Excitable membranes changes
-Reduced effectiveness of hormones, drugs, and enzymes
- ✔✔ANSWER ✔✔-Changes in pH can affect:
acid-base imbalance. - ✔✔ANSWER ✔✔-Arterial Blood
Gas "ABG" is used to determine
-pH 7.35-7.45
-CO2 35-45 (CO2 is an acid, higher the number = more
acidic blood is)
-HCO3 22-26 (bicarbonate) - ✔✔ANSWER ✔✔-3 Parts to
an ABG:
renal system compensates. - ✔✔ANSWER ✔✔-
Respiratory issue=
lungs compensate - ✔✔ANSWER ✔✔-Metabolic issue=
, -Incomplete breakdown of glucose
-Breakdown of protein and fats
-Destruction of cells. - ✔✔ANSWER ✔✔-Acids
-Weak base
-Major buffer of extracellular fluid (ECF)
-From intestinal absorption of ingested bicarbonate into
ECF, kidney absorption and breakdown of carbonic acid.
-70-80% is excreted in stool. - ✔✔ANSWER ✔✔-
Bicarbonate
-Body attempts to correct blood ph changes.
-Ph <6.9 or >7.8 is usually fatal.
-Respiratory system more sensitive to acid-base changes;
can begin compensating in seconds to minutes.
-Kidneys more powerful; result in rapid changes in ECF
composition; fully triggered for an imbalance takes
several hours to days. - ✔✔ANSWER ✔✔-Compensation
too much base. - ✔✔ANSWER ✔✔-Metabolic Alkalosis =
